Rocks and Minerals
The three types of rocks
Sedimentary, Igneous, Metamorphic
The type of plate boundary responsible for mid-ocean ridges
Divergent
The early stage of an stars life is spend in a region (on the Properties of Stars chart) called this
The main sequence
Glaciers
The shortest lived fossil group in Earth history
Placoderm fish
A sedimentary rock composed of grains of sand
Sandstone
Puzzle fit of continents, matching fossils on different continents and evidence of glaciers in warm environments all support the idea that this once existed
Pangaea
The process by which light elements join together to form heavier elements and energy within a star is called this
Nuclear fusion
This type of weathering causes material to become small but keep its chemical composition unchanged
Physical (or mechanical)
The gas in Earth's atmosphere which was not present until it was created by cyanobacteria and released from the ocean
Oxygen
The physical properties of a mineral are determined by this
Its internal arrangement of atoms
S waves are not received directly opposite an Earthquakes point of origin (focus) because they cannot travel through this
Liquids
The season in which Earth is furthest from the sun
Summer
Rusting of iron is an example of this type of weathering
Chemical
An igneous intrusion which passes through three layers of rock is this relative age, compared to the rock it's passing through
Younger
Recrystallization is the process that creates these
Metamorphic rocks
Trenches, island arcs and volcanoes are all associated with this type of plate boundary
Convergent
The moon phase in which the entire lit up side is facing away from the Earth
New moon
Triangle shaped deposits at the end of a river are called this
Deltas
One process involved in the creation of a geologic unconformity
Uplift, Weathering, Erosion or Submergence
A mineral which bubbles with acid when powdered
Dolomite
This is caused by underwater earthquakes
Tsunamis
This moon phase always results in Earth experiencing spring tide, and may result in a lunar eclipse
Full moon
The landscape region in which we can find Queens, NY and the rest of Long Island
Atlantic Coastal Plain
The geologic era in which humans first appeared on the Earth
Cenozoic
